To all whom itnadycon c ernr Beit known that :I, HARRY J. ANDERSON,

a citizen of the United States," residing at Chicago, in the county of Cook and State of 6 Illinois, have invented; a" certain new and useful Improvement in'Mechanical Musical Instruments, of which the following is'a fullyclear, concisefan'd exact description, 1 1 reference beingahad' to theaccompanying drawings, for1ning a part ofthis specification, invention relates to the mechanism of aniautoma'tic musical instrument,*and has as one of its objects'the pro-v'ision'of a device in mechanism may be mounted upon. a single support sothatthe whole may be installed or removed from theinstrument in the easiest manner posslble and also topermit the} 1n- 7 spection of the interior without disconnecting-such-Iparts from theinstrument.

1 Afurther object is to arrange the partsin asymmetrical manner so that passages be tween the bellows and the operating mecha-' nisms shalliibe of equaldength, while providing an efiicient and practical arrange-v ment for varying th'evtone or the time of the music. I. v

Ihroughout the drawings similar} referen'ce characters denote the same part; a

Referring more particularly ,tothe draw-s ings,,l1,and 1 are base members which are hinged to the toe rail 2,015 the pianoasi shown" atl3'.gc fllhe-- members 1 and 1 carry the -wholeim echanism with which this inven' 1,1; tionhas to deal; Uponthe' back ofgthe c onnectedvby meansof. ports 5.1withthe'inte; 7

Parallel with passages 6 and? is a passage 8 formed n a similar manner, but'divided into four sections by three blocks such as 9, whereas passages 6 and 7' are uninterrupted throughout their entire "length. A board orplate 37 covers "the passages 6,7 and 8. i a 'At the outer ends of members land 1 are the usual reservoir pneumatics10 10, a covering the ends of the passages 6, 7 and *8,-

Chamber 16 con nects with passage 7 by the port 23 and with 1 chamber+19 by the port 24, while chamber 17. connects with passage Sby the port 25,1 and withchamber 20 by the port 26} A passage 27 leads from'chamber 18 tothe key strik ing' -mech-anism,and passage 28 leads from' connect chambers '18, 1,9 and 20 andjpassage,

It will be understood that valveBO is al- Iways closed when 29 is open, and vice versa.
